TheChang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh mygoodness, did they succeed. This is awesome.

嫦娥2号飞越图塔蒂斯成功地获得图像。我的天啊，他们刚成功。太棒了。



Chang'E2 images of Toutatis

图塔蒂斯的嫦娥2号图像

The closest fly-by was at 08:30:09 UTCon December 13 at an altitude of just 3.2 km and at a relative velocity of10.73 km/s. Quite a few photos were snapped by the CCD camera - including this seriesof photos taken 93 - 240 km away from Toutatis:

距离最近的飞越是在协调世界时十二月十三日08:30:09，距小行星仅有3.2公里，相对速度为10.73公里/秒。利用星载CCD相机拍摄了相当多的照片，包括这一系列距离图塔蒂斯93 - 240公里的照片：


Theimages are much better than I expected them to be. There are also many more ofthem than I expected. I look forward to learning more about how they wereacquired!
这些图像质量比我预料他们做的要好得多。也比我自己所期望的要好得多。我期待着更多地了解他们是如何捕捉到的细节！

These,in combination with the incredible radar images still being acquired fromGoldstone and innumerable optical observations, make Toutatis one of thebest-studied asteroids in the solar system.

结合这些通过金石系统和无数光学观测获得的难以置信的雷达图像，使图塔蒂斯成为太阳系中研究最透彻的小行星。


I'll have more to write about this in thefuture, but I wanted to share the news as soon as I heard it! Today, we needgood news.
我本来想以后再写更多的关于这件事的博文，但是当我听见这个消息时我想马上分享！今天，我们需要好消息。

Many thanks to users yaohua2000 and CosmicPenguin at unmannedspaceflight.com for bringing this to Western attention!

Excellent news! Congratulations to the Chang'E people and all the Chinese!
好消息！祝贺“嫦娥”人和所有的中国人！

Very impressive. The scientists and engineers involved should be veryproud, especially considering that Chang-E wasn't designed to do this sort ofimaging. My hat is off to them.
非常令人印象深刻。参与的科学家和工程师应该很骄傲，特别是考虑到“嫦娥”不是用来做这种成像。我很佩服他们。

Ethan Walker: 12/14/2012 09:01 CST
Awesome! these sorts of mission extensions also show that China'sexploration program is maturing rapidly. I was wondering though about thecolor. I might expect a slightly reddish color, but that is really quitepronounced. I'm surprised Chang'E was even equipped with a color camera!
太棒了！这些延长的各种各样的任务也表明中国的探测计划迅速走向成熟。尽管我对颜色不是太满意。可能我想象中颜色稍微偏红点，但很明显那是真的。我很惊讶，“嫦娥”甚至安装了彩色摄像机！

Andrey Mezentsev: 12/14/2012 09:10 CST
Quite acceptable, congratulations!
非常令人满意，祝贺！

Given the sheer quantity of images, I am assuming we are seeing photosshot using the webcam-style cameras they used to monitor rocket firings andsolar panel deployments (seehttp://www.planetary.org/blogs/emily-lakdawalla/20... -- and I notice I havesome import errors to clean up in that post.)
鉴于绝对海量的图像，我假设我们将看到使用他们用来监测火箭点火和太阳能电池板的调度的互联网同步摄相机拍摄的照片（参见http://www.planetary.org/blogs/emily-lakdawalla/20...——我发现在这片报道里有一些输入错误需要被清除。）

I also picked up the word TOOO-tah-teess in the Chinese broadcast.
我也在中国的广播中听到了“图-塔-蒂-斯”这个词。
